Title: Watercraft drive unit arranged to be pivotable, in particular for motor and sailing yachts and amphibious craft
Inventor: ZIKELI FRIEDRICH DIPL ING
IPC: B63H5/18
Filed: 1987-05-29
Abstract: The invention is based on the object of arranging the drive unit (gear train (1), propeller shaft (3) and propeller (11)) of a watercraft so that it can pivot about its drive shaft (2) or axis of symmetry (A-A) from the working position into the inoperative position in the pressure tank or caisson (10) fitted above it. This arrangement provides substantial advantages:   - When sailing, towing, or transporting on land on a trailer or otherwise, the drive unit is pivoted into a protected position within the vessel, and has no braking effect. - In this position, maintenance and repair work can be performed on the drive unit from within the vessel; the vessel can continue in operation while doing so. - There is a laminar flow of water along the submerged hull and the gear train cover (5), and thus a minimum loss of energy. - The pressure tank (10) also represents an additional buoyancy tank for the vessel. - In the inoperative position, the propeller does not windmill when idling, as is otherwise the case when the vessel is moving under sail or being towed. - The link to the engine (21) does not need to be interrupted in order to move the drive unit from the working to the inoperative position.   The object is achieved in making the drive unit (1) of the watercraft revolvable on its journals (6 and 7) in the hollow shafts (8 and 9) ... Original abstract incomplete. <IMAGE>

Patent DE-3736809-A1 (DE)
Title: Method and device for measuring the drum load, in particular in domestic washing machines and spin dryers
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F33/48
Filed: 1987-10-30
Abstract: In known methods, the fluctuations in the actual values of speed of revolution of the motor or the power consumption behaviour of the motor are used to measure the drum load or the unbalance of the washing. Interference variables such as for example the slip losses of the drive belt are not taken into account and falsify the measurement. The new method eliminates these interference variables and supplies a very accurate measurement result. The drum load or unbalance is determined in the new method by means of a torque measurement. For this purpose, an intrinsically rotatable coupling element is located between the drive wheel of the drum and the shaft of the washing drum. The angle of rotation of the coupling element is a measure of the necessary torque. The new method can be used for domestic washing machines and spin dryers and serves to optimise the washing or spinning program.

Patent DE-3813654-A1 (DE)
Title: Circulation pump
Inventor: PATZELT SIEGFRIED
IPC: F24D19/08
Filed: 1988-04-22
Abstract: The housing of the circulation pump is to contain a space for separating the gas or air bubbles entrained in the delivery medium, the shape of which space is configured as uncomplicated as possible and consequently can be produced with the least possible technical expenditure. On the other hand, the shape of the space is to guarantee reliable gas separation. On the intake side, the pump housing is widened to a smooth-faced space of larger volume, in which the flow rate of the delivery medium is reduced, with the result that entrained gas bubbles are separated. The separation space is directly connected to a gas-separating valve.   Circular pumps for water-heating installations. <IMAGE>

Patent DE-3831294-A1 (DE)
Inventor: MAIER URS
IPC: B24B17/02
Filed: 1988-09-14
Abstract: Provided before a method consisting of precision grinding with subsequent finish grinding is a grinding phase in which the grinding belt (21) is movably pressed under predetermined pressure against the outer surface (45') of the preheated cylinder (45) to be machined within a certain clearance X or X', adjustable by means of an adjusting device (30), between a copying template (10) and a contact roller (23) in such a way that, in this preliminary grinding phase, stock is uniformly removed from the cylinder surface (45') irrespective of its geometry. After a surface layer of the cylinder (45) formed from various particles has been ground down, the proportional pressures applied to the belt-grinding unit (1) are changed in such a way that, in the now following first grinding phase, the actual precision grinding, a fixed connection is set between the copying template (10) and the contact roller (30). A uniform distribution of temperature and thus also a uniform expansion of the cylinder surface (45'), which is of importance especially in the radial direction, are thereby ensured, as a result of which a more accurate cylinder geometry is achieved. <IMAGE>

Title: Sampling cooler
Inventor: SCHMOLE MICHAEL DIPL ING
IPC: G01N1/22
Filed: 1988-12-29
Abstract: In sampling coolers which have a pipe coil inside a container, there arises the problem of scaling of the pipe coil. To avoid this problem, according to the invention, a first part (25a) of the conduit (25) for the material to be measured is arranged as a pipe coil on the outside of the container (10), in order to carry out pre-cooling. A second part (25c) of the conduit for the material to be measured runs the container (10). When the material to be measured reaches the second part (25c), it is already so far cooled down that no significant scaling occurs in the interior of the container. The cooling of the outer part (25a) is carried out via the container wall (22), via the environmental air and via evaporation cooling of the air condensate. <IMAGE>
